Advertisements So basically I have a simple code where im working with square matrix, where either the matrix is generated randomly, or the user can input the numbers in matrix, but when i enter the size of it for example in this do-while: do { printf("Define the size of the matrix: "); scanf("%d", &n); }… Read More How can I fix any letter or overall character input in integer input

Advertisements I’m currently working on an assignment where I have to ask the user to input 5 Blood Pressure readings within a certain range (>=40 and <= 100). I’m trying to create an input validation using a do-while loop within the for loop that scans those inputs to an array. While I am getting an… Read More do-while input validation within array for loop

Advertisements I am having the following program in c++; #include <iostream> int main() { int i=1, j=1, k=1, z=0; for (; i <= 10; i++) while(j <= 10) { j++; do { k++; z++; } while(k <= 10); } std::cout << z << " "; } The output is 19 when running and I cannot… Read More Why the output of z variable is 19? How does that code works more clearly?

Advertisements I’m writing a script which reads variables from the columns of one file, pattern matches with a column of another file, and prints whole lines from this other file to an output file. I think I’ve come close to a solution, but only column names in the file outputs are produced (NR==1 is written,… Read More Awk in do-while loop, read files with multiple columns

I am trying to use a do while loop but do not know where to enter the variable in the loop? public static void… Read More Do while loop determined by users input c#

Advertisements Feel dumb, but having coded for 10+ years, haven’t used a do-while loop in the last 9. For the life of me, I cannot figure out why this is returning 1 instead of const getNextEventCountTest = () => { let sum = 0; let q = 0; do { sum = sum + 0.5… Read More do-while loop is not behaving as expected

Advertisements For an assignment, I had to make a program to see if the user input contained any of the three letters: r, c or p. If it was wrong, I had to keep asking the user to retype the input until the user typed the correct answer.[] I tried using a do while loop… Read More Do-while loop doesn't work for validating using a .equals method (Java)

Advertisements I’m trying to achieve the following: Get appscript to recognise the latest csv file within a folder in google drive. Once it does recognise it, it will import the file into google sheets. If a file has been previously uploaded to the sheet, appscript should upload the new lines below the currently existing lines.… Read More unable to get a do-while loop working inside an if-else statement using google appscript

Advertisements The series: 1×2 + 2×3×4 + … + n×(n + 1)× … ×2n For example, if you enter 3, the output should be 386, because (1×2)+(2×3×4)+(3×4×5×6)=386. I’ve tried various loops, but that is not even close to the desired result. Though, I’ll post it here: int sum = 0, n = sc.nextInt(); for (int… Read More Calculate the sum of the series based on a given number in Java
